The best I have seen for sale in person are the antique deer antlers at B.D. Jeffries in Atlanta. A great store (while overpriced) that somehow merges antiques and Longchamp purses.
And even though Domino's blog claims that antlers are over, the August 2008 issue shows the small antlers on plaques. This is at Thom Filicia's cottage (loved him in Queer Eye for the Straight Guy, love him even more now). So again, in the right context these antlers are so perfect.
Also in Alice Turner's farmhouse from the August Domino. Very different look.
You can always find a ridiculous deal on eBay and the Black Forest Antlers (as they are most often referred to) are no exception. $95! for 4!
